How to Create a Portal in Minecraft: Nether, End, and More

Portals are one of Minecraft's most iconic features — glowing gateways that teleport you between dimensions or across vast distances. Whether you're diving into the fiery Nether, hunting the End Dragon, or using mods to add custom portals, the process for each type is distinct. Here's a clear breakdown of how each portal works, what you need to build one, and what affects how well they function in your game.

The Two Main Portals in Vanilla Minecraft

Before gathering materials, it helps to know which portal you're actually building. Vanilla Minecraft — the unmodified version — has two buildable portals: the Nether Portal and the End Portal. They work very differently and require different resources and stages of the game.

How to Build a Nether Portal 🔥

The Nether Portal is the most common portal players build. It transports you to the Nether dimension, a dangerous underworld filled with lava, hostile mobs, and valuable resources like Netherite and Blaze Rods.

Materials Needed

• Obsidian — at minimum 10 blocks (for the smallest valid portal), up to 14 blocks for a full frame
• Flint and Steel or a Fire Charge — to activate the portal

Step-by-Step Construction

1. Gather Obsidian. Obsidian forms naturally where water flows over lava source blocks. You can also pour water over a lava pool yourself. You need a Diamond or Netherite pickaxe to mine it — no other tool works.
2. Build the frame. The minimum portal size is 4 blocks wide × 5 blocks tall (including corners), which uses 10 obsidian. You can build larger portals — up to 23×23 — but the minimum is the most resource-efficient.
3. Ignore the corners (optional). The four corner blocks of the frame don't need to be obsidian. Any solid block — or even nothing — can fill the corners, and the portal will still activate.
4. Light it. Stand inside the frame and use Flint and Steel (or a Fire Charge) on any interior surface of the frame. Purple, swirling portal blocks will fill the opening within a second.
5. Step through. Walking into the portal for about 4 seconds initiates the transport. You'll arrive at a corresponding location in the Nether.

Nether Portal Linking and Distance

One important technical detail: the Nether and Overworld use an 8:1 distance ratio. One block of travel in the Nether equals eight blocks in the Overworld. This matters when building portal networks — if portals aren't spaced correctly, the game may link them to unexpected exit points.

How to Build an End Portal

The End Portal is different in a key way: you cannot build it from scratch in Survival mode. End Portals exist only in Strongholds, underground structures generated in every world. You find one using Eyes of Ender.

Activating the End Portal

1. Craft Eyes of Ender — each requires one Blaze Powder and one Ender Pearl.
2. Throw an Eye of Ender into the air. It floats toward the nearest Stronghold. Follow it.
3. Locate the Portal Room inside the Stronghold. It contains a 3×3 End Portal frame made of End Portal Frame blocks — these cannot be obtained or placed in Survival without commands.
4. Fill the frame. Each of the 12 frame blocks has a slot. Insert an Eye of Ender into any empty slots (some may already be filled when you find it). Once all 12 are filled, the portal activates.
5. Jump in. Unlike the Nether Portal, the End Portal is instant — no waiting period.

Can You Build an End Portal in Creative Mode?

Yes. In Creative mode, you can place End Portal Frame blocks and Eyes of Ender directly from your inventory. The activation logic is the same — fill all 12 frame slots. This is the only way to construct a functional End Portal outside a Stronghold.

Portal Variables That Affect Your Experience

Not all portal setups behave identically. Several factors influence how portals work in practice:

Java vs. Bedrock: Portal Differences Worth Knowing 🎮

Java Edition and Bedrock Edition (Windows, console, mobile) handle Nether Portal linking through different algorithms. Java uses a more precise coordinate-matching system, while Bedrock can sometimes link portals less predictably across long distances. If you're building a portal network for fast travel, understanding your edition's linking behavior matters more than the portal construction itself.

What About Mod Portals?

Popular mods like Twilight Forest, Aether, and various dimensional mods introduce their own portal types with unique frame materials and activation methods. For example, the Twilight Forest portal is activated by placing flowers around a 2×2 water pool — no obsidian needed. These portals are entirely mod-defined, so the rules vary depending on which mod is installed and its current version.

The Variables That Determine Your Next Step

Building the portal frame is the straightforward part. What shapes your actual experience is the combination of factors unique to your situation — which edition you're playing, whether you're in Survival or Creative, how far along in the game you are, and whether mods are involved. Someone on a modded Java server with a portal network faces a completely different set of decisions than a Bedrock player entering the Nether for the first time.
